Abstract：This paper mainly introduces rim stiffness influence on vehicle NVH. Through the analysis of the relationship of rim size， weight and stiffness， the finite element analysis was carried out on the design of multiple sets of rim， and the article summed up the design method to improve the wheel stiffness effectively and to realize the lightweight design method to the greatest extent.
